ble portion lying wholly within the contour of the out departing of the advantages of the invention.

In the `accompanying drawing forming part of this specification,

Figure 1 is a front elevation of a bottle neck showing a crown cap constructed in accordance with the invention applied thereto.

n Figure 2 is a perspective View of the parts shown in Figure 1, with the ange of the cap partly ripped away providing a tapered strip by lmelns of which the cap may be jerked from the Figure 3 is an enlarged detail sectional View taken on the line 3 3 of Figure 1.

Figure 4 is a front elevation of a modified form of the invention, in applied position.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the reference numeral I sealing a bottle or like conwhile at the same time being suciently frangible to permit being readily torn or ripped manually by the ngers without the use of tools such as the conventional bottle cap remover.

The cap is ,provided on the underneath side with a gasket i4 which is comi-ned against the beading I5 on the neck of the bottle by means of the crixnps of the ange engaging underneath the beading. The gasket seals the bottle pressure and leak tight.

cumrerentially and obliquely upward from a point I 'I where the ange I3 engages underneath the beading I5 on the neck of the bottle to a point I8 substantially above where the flange disengages from underneath the beading, as shown in Figure 2 and Figure 3. 'Ihus the line of indentations provides a weakened portion of the iiange extending obliquely upward and progressing from beading at its low end to a point at its upper end where it may be said the iiange disengages from underneath the beading entirely. A

A cut I 9 of rectilinear or triangular contour is formed in the ange and extends from the edge of the ange to the low end of the line of indenbest shown in Figure 2. tapers from the cut I1 to its wide end 2| at the high end of the line of indentations I6. This tapered strip provides a grip which may be forced transversely across the disc I2 of the cap to jerk the cap from the bottle. Since the ripping operation along the line of indentations I6 has already partly removed the crimped flange along a considerable portion thereof from its engagement underneath the beading I5, a very slight pull upon the tapered strip 20 will be sumcient to easily lift the cap from the bottle.

In Figure 4 there is shown a modied form of the invention' in which the cap is identically the same as above described, and hence has been given similar reference numerals with the single exception that the line of indentations I6 is continued beyond the cut I9, as shown at 22. The purpose of this is to permit an additional strip 23 to be ripped off the ange thereby disengaging thecrimped Hange from underneath the beading along an arcuate distance substantially twice as great as the form of the invention shown in Figures 1 and 2.

By crown cap in the specication is meant a bottle stopper composed of a sealing disc gasket and a metallic sealing cap encircling the periphery of the disc gasket and having a ange adapted to be bent into locking contact with the beading upon the neck of the bottle, the flange being crimped to provide corrugations which afford circumferential resiliency.

From the above description it is thought that the construction and operation of the invention severing operation producing a tion.

What is claimed fs:

1. A crown cap for application to bottles and like containers by conventional bottling machines, including 'a sealing disc gasket, and a metallic sealing cap encircling the periphery of the disc gasket and having a flange adapted to be bent into locking contact with the beading upon the neck of the bottle, said flange being crimped or corrugated to afford circumferential resiliency, the crimped flange being provided with a line of indentations extending circumferentially and obliquely upward from a point where the flange engages underneath the beading on the neck of the bottle to a underneath the beading, cut extending from the free edge thereof upward to the low end of the line of indentations to permit the flange being ripped and severed along the oblique line of'indentations, the ripping and tapered strip by means of which the cap may be jerked from the bottle.

2. A crown cap for application to bottles and like containers by conventional bottling machines, including a sealing disc gasket, and a metallic sealing cap encircling the periphery of the disc gasket and having a flange adapted to be bent into locking contact with the beading on the neck of the bottle, said flange being crimped or corrugated .to afford circumferential resiliency, the crimped flange being provided with lines of indentations extending in opposite directions circumferentially and obliquely upward from a common point where the flange engages underneath the beading on the neck of the bottle to points substantially above where the flange disengages from underneath thebeading, said ange having a cut extending from the edge thereof upward to said common point at the low ends of the lines of indentations to permit the flange being ripped and severed along the oblique lines of indentations, the ripping and severing operation producing a plurality of spaced tapered strips by means of which the cap may be jerked from the bottle.

3. A closure for a bottle having a beaded neck, comprising a metal cap having a disc portion and an integral dependingjlange having downwardly and outwardly extending flutes adapted to be crimped underneath the beading of the bottle neck, and a fluted tongue adapted to be torn along'the flange for an angular distance of a quadrant more or less circumferentially around the flange and defined by the edge of the flange and by a line of indentations passing obliquely across a plurality of contiguous flutes and terminating adjacent to the tip of the flnal flute embraced by the tongue, the indentations thus passing obliquely across the beading of the bottle neck, the tongue when severed along said indenvtations disengaging from underneath said beading and forming a long grip cap from the bottle neck.

4. A closure for a bottle having a beaded neck` comprising a metal ycap having a disc portion and an integral depending flange having a portion provided with downwardly and outwardly extending flutes adapted to be crimped underneath the beading of the bottle neck, and a pair of circumferential lines of indentations extendfor dislodging the -and an integral depending point sub-y` stantially above where the flange disengages fror" said flange having will be fully understood without further explanaing in opposite directions from a common point on the fluted portion of the flange obllquely upward across the beading of the bottle neck and through a plurality of contiguous flutes, said line of indentations passing out of the fluted portion of the flange remote from said common point and permitting of a pair of tapered fluted flange from said common point circumferentially of the flange in opposite directions to form a pair of oppositely disposed long grips for dislodging the cap from the bottle neck.

5. A closure for a bottle having a beaded neck, comprising a metal cap having a, disc portion flange having downwardly and outwardly extending flutes adapted to be crimped underneath the beading of the bottle neck, a circumferentially extending tapered tongue defined by a line ing circumferentially of the cap in the flutes and being disposed obliquely upward across the beading of the bottle neck and across the flutes from about midway of the ends of one of the flutes to above the flnal flute embraced by the tongue, and an inverted V-shaped opening formed in the edge of the flange and extending at the apex to the beginning of said line of indentations for admitting a tearing means tongue to be severed along tions and dislodged from underneath the bead# ing of the bottle neck for effecting removal of the cap.

6. A closure for a bottle having a beaded neck, comprising a metal cap having a disc portion and having a depending flange of uniform width throughout and provided with downwardly and outwardly extending flutes beginning at the lower edge of the flange and terminating at a point near the disc portion, and a tongue forming a fluted grip for dislodging the cap and extending circumferentially along the edge portion of said flange, said tongue including a plurality of the flutes for an angular distance of about a quadrant more or less of the circumference of the flange and being defined at theupper longitudinal edge by a frangible line of indentations in the flange extending from one of the flutes obliquely upwardly across the beading of the bottle neck and terminating abo've the final flute forming the tongue.

'7. -A crown cap for application to bottles and like containers by conventional bottling rha-l the line of indendations to permit the flange being ripped and severed along the line of indentations, the ripping and severing operation producing a crimped strip by means of which the cap may be jerked from the bottle, the portion of the cap forming the strip being normally located not to project below the normal bottom edge of the cap.
